To all whom it may concern:

. Be it known that I, I-IENTIR SARAFIAN, of the city of New York,borough of Manhattan, in the county and State of New York, have inventednew and useful Improvements in Lamp-Wicks, of which the following is afull, clear, and exact description.

My invention relates to lamp-wicks, and has for its object to provide awick which will be incombustible, which will not char or clog up, andwill require no trimming .or adjustment. To this end I construct thewick as fully described hereinafter and specifically pointed out in theclaims.

Reference is to be had to the accompanying drawings, forminga part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the figures.

Figure 1 is a front elevation of the improved wick. Fig. 2 is asectional elevation thereof, and Fig. 3 is a cross-sectional elevation.

As illustrated in the drawings, the improved wick comprises fiveparts-viz., the wick proper, A, the wire-gauze cap B, the millboard orfilter-tip C, the asbestos filling D, and the shield or guard E. I

The wick proper, A, may be of any suitable material. Itmay be flat, asshown; but myinvention is applicable to round wicks as well.

The wire-gauze cap B is U-shaped in crosssection to embrace the top ofthe wick A, and consists of cross-wires B and longitudinal The ends ofthe latter protrude beyond the lowermost cross-wire and are preferablysharpened, as shown. These ends are clenched into the wick A, so as topoint upward, (see Fig. 3,) forming return members or hooks 13 I therebyobtain a very firm connection of the cap B with the wick proper, A,since the hooks B will prevent the cap B from being pulled from thewick.

The space between the top of the wick A and the horizontal member orbend B of the cap 13 is filled by the filter-tip O, the asbestos fillingD, and the shield or guard E.

The filter-tip C is a strip of millboard or other suitable material. Itis located in contact with the top or bend B" of the cap 13.

The filling D consists of loose asbestos, which is in contact with thetop of the wick A and with the tip C, preferably at the bot tom andatboth sides, as shown in Fig. 3. The shield or guard E is embedded in theasbestos filling D between the filter-ti p O and the wickA and out ofcontact with each of them. This guard should not be bulky, since then itwould interfere with the capillary attraction, and preferably Iconstruct it of one or more strips of wire or metal='for instance; acoil of wire-as will be seen best in Fig. 2 The guard extendshorizontally or trans versely of the wick and will have a tendency toabsorb the heat and to conduct it horiz'ontally toward the sides of thewick instead of allowing it to spread downward. This guard intransferring the heat from the middle of the wickto the exterior wallsof the same dissipates the heat laterally through the wick to suchpoints as are exposed to the air, whence it may in great part beradiated.

It will be seen that 'theconnection of the cap 13 with the wick A isvery strong, and that said connection is effected by hook or returnmembers B of the cap itself.

The filter-tip O insures a steady and clear that may have passed up thewick A and asbestos filling D.

The guard E prevents the heat of the flame from striking too muchdownward and injuriously affecting the top of the wick A. Furthermore,the guard prevents the loose asbestos from packing together too close,and thus contributes to secure an ample feed of fuel by capillarity.

'In defining myinvention with greater clearness I would state that I amaware that Oommodore D. vRundell, in his application for a patent filedJanuary 16, 1899, Serial No. 702,224, (which application has beenassigned to me,) has shown, described, and claimed a lamp-wickcomprising four essential elements-via, a body portion of cloth, arelatively -narrow upper end of asbestos millboard, a packing of loosemineral fiber between the end of the cloth wick and the millboard crown,and an inclosing and retaining sheath of gauze-wire extending along bothsides and over the end of the wick and conmeeting and retaining theseveral elements in unitary structure as a separate, complete,

flame, since it acts to retain any impurities and self-sustainingarticle of manufacture adapted to fit any lamp. I wish, therefore, tostate that I do not lay claim to the invention of this broad idea.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. A lamp-wick, comprising a wick proper, aperforated cap embracing the top of the wick and projecting upwardlybeyond the same, a filter-ti p located at the top of the cap, and anasbestos filling engaging the wick proper, the cap, and the side surfaceas well as the bottom of the tip.

2. A lamp-wick, comprising a wick proper, an incombustible tip therefor,a perforated cap embracing the tip and the top of the wick proper, and ashield or guard extendinghorizontally within the tip between the cap andthe top of the wick proper at a distance from the upper edge of the tip.

3. A lainpqvick, comprising a wick proper, an incombustible tiptherefor, a perforated cap embracing the tip and the top of the wickproper, and a shield or guard located within the tip between the cap andthe top of the wick proper, said guard consisting of a coiled wire withthe axis of the coil disposed horizontally.

4. A lam p-wick, comprising a wick proper,

a perforated cap embracing the top of the wick and projecting upwardlybeyond the same, a filter-tip located at the top of the cap, an asbestosfilling between the cap, tip, and top of wick proper, and ahorizontally-extending shield or guard embedded in said filling betweenthe tip and the wick proper.

5. A lamp-wick, comprising a wick proper, a perforated cap embracing thetop of the wick and projecting upwardly beyond the same, a filter-tiplocated at the top of the cap, an asbestos filling between the cap, tip,and top of wick proper, and a coiled wire embedded in the said fillingbetween the tip and the wick proper, and out of contact with each ofthem the axis of the coil being horizontal.

6. A lamp-wick, comprising a wick proper, a perforated cap embracing thetop of the wick and projecting upwardly beyond the same, a filter-tiplocated centrally at the top of the cap, with a space interveningbetween the sides of the cap and those of the tip, and an asbestosfilling engaging the wick proper, the cap, and both side surfaces, aswell as the bottom of the tip.
